“Yet, regrettably, he was not forthcoming with such information related to the Sochi Games. It is surprising to hear these views so many months after the Commission concluded its work.”

Natalia Zhelanova, anti-doping advisor to the Russian Minister of Sport, said: “Russia acknowledges the importance of stamping out doping, and we are doing everything we can to achieve this. We acknowledge there are issues with doping in Russia, just as there are across the world.

“We are cooperating with a wide range of anti-doping organisations in these efforts, including Wada, and have nothing to hide in the fight against doping.”

Russia won 13 gold medals at the Sochi Winter Olympics. The names of the alleged drug cheats were not revealed in the CBS programme.

The same report said Rodchenkov was complicit, asking for and accepting bribes and destroying blood and urine samples. He later resigned from his role as head of the Moscow lab.

Stepanov and his wife, banned athlete Yuliya Stepanova, were the main whistleblowers in a series of German television documentaries in 2014 which alleged “99%” of Russian athletes were doping. Those claims led to the Wada independent commission being set up.

The IAAF is meeting next month to assess whether Russia has done enough to tackle its doping culture before being allowed to take part in August’s Olympic Games in Rio.
